填充墙框架结构抗震目标性能水平研究
|
摘要
填充墙作为非结构构件,仍然参与结构抗震作用。综合考虑填充墙与主体结构之间的相互作用,采用修正等效斜撑压杆模拟填充墙,在Open SEES平台上建立填充墙框架简化模型。以最大层间位移角为地震需求参数,对简化模型进行增量动力分析,确定与填充墙框架极限状态相协调的抗震性能目标,并与纯框架性能及GB 50011—2001《建筑抗震设计规范》的3个性能水平进行比较,结果表明,填充墙的存在能显著提高主体结构的抗侧刚度,进而改善结构的抗震性能。
Infill walls are considered as non-structural elements,but they are still involved in seismic calculation.This paper considered the interaction between the main structures and fill walls,used Open SEES to establish simplified model.Infill wall adopted improved equivalent slant strut based on FEMA model.Considering maximum drift as seismic demand parameter,incremental dynamic analysis was performed to obtain infilled RC frame's threshold values on target performance levels.Comparing the calculated results with pure framework and codes,it was indicated that the presence of infill walls could significantly improve lateral stiffness of frame structure and its seismic performance.
